As a new type of wireless ad hoc network,sensor network has a broad applied prospect in many fields,such as military monitoring,earthquake and whether forecasting.Based on the idea of square grid partition,a directional algorithm of wireless sensor is put forward.In this new algorithm,the sink node first divides the target area into square grid,then spreads the divided information to all the sensor nodes in the network,and constructs the approximately minimal connected cover set in the target area,and then the node which is closest to the sink node is identified in this algorithm,and the relative length is counted,and based on the relative length,some routines which consume the least energy are constructed.During the data transition,the dormancy mechanism is adopted to carry out the direction sensor.The algorithm analysis and simulation experiment manifests that the new algorithm,compared with algorithm of the energy aware routing,is more advantageous in the network lifespan.
